Paid time off, in the form of vacation days, sick days, and other forms of paid absences, are ways to help employees manage issues associated with health, school, leisure, or any other non-work activity. Many employers now allow employees to draw leave time from a single pool for any type of leave rather than allowing only a fixed number of days for each type of absence. Leaves and time-off programs include paid and unpaid authorized leaves such as sabbaticals, social service leaves, leaves for emergencies, paid leave banks, and family-care leaves. Many employees want and need leaves in addition to annual vacations for reasons such as care of newborns or sick family members and for personal interests or volunteer work. These leaves are different from flexible work schedules in that flextime addresses when and where the work gets done; time-off programs provide employees with leave during unusual or emergency times. Many companies provide this benefit by leave-sharing programs. These allow employees to voluntarily donate their paid time off to coworkers. Companies may also offer paid leave banks in which employees are given a single pool of time off to use for vacations, personal time, illnesses, and family emergencies. Employers using paid leave banks do so to provide flexibility to employees and to assist managers in scheduling time off. However, the availability of more flexibility for leave time may hinder the organization if key employees are absent when needed, and thus, these programs must be properly managed.
